Abstract: Disclosed is a method for improving model-free adaptive control. The method, based on a multiple-input and multiple-output system, for improving compact-form dynamic linearization model-free adaptive control (CFDL-MFAC) belongs to the field of control algorithm design. Firstly, proportional control is added to CFDL-MFAC to solve the problems of a low response speed and a large overshoot of an original control system; secondly, an actuator anti-saturation control algorithm is added to the above control structure, such that an actuator does not carry out an over-limit operation upon reaching an upper-limit saturation or a lower-limit saturation, and when a control instruction enters an unsaturated area again, the actuator can quickly give a control response, thereby improving the control precision of the system; then, it is proven by means of rigorous analysis that the improved control algorithm can ensure tracking error and BIBO stability under a certain condition; and finally, the control algorithm is applied to an aero-engine control system, and the effectiveness and the advantages of the control algorithm can be obtained by means of numerical experiments.
